If you've never seen a Noctua heatsink, the first thing you wil l notice is the quality of the material used. Many heatsinks are now desi gned after the NH-U12 with a copper base attached to heatpipes that lead to aluminum fins, but when comparing them side-by-side it is clear that t he Noctua fins are stronger, thicker and very difficult to bend. Today we will be looking at the Noctua NH-U12P, a revised version of the original NH-U12. The 12P has several improvements over its older sibling, some lead to better performance and some to making the installation easi er and more diverse.
